Abstract:
The submucous plexus of the gastrointestinal tract in 20 guinea pigs were studied by histochemical methods for Nissl bodies and acetylcholinesterase (AChE) and immunohistochemieal technique for somatostatin (SOM). We found that some neurons in the submueous plexus were located against the lymphatic vessels or even protruded toward the lumen, and only a basement membrane separated the endotheliocytes from the neurons. Thus we refer them as "paralymphatic neurons". The neurons were spindle, pear-like or polygonal in shape and all showed AChE positive reaction, but some of them exhibited SOM positive reaction. So, the paralymphatie neurons were different in property. According to the close appositional relationship between the neurons and lymphatic vessels, we infer that this peculiar type of neurons might be similar to the "cerebrospinal fluid-contacting neurons" in the ependyma and might have the function of neurosecretion or reception of the changes of chemical composition in the lymph. Paralymphatie neurons existed mainly in small intestine, rarely in colon and were not seen in gastric corpus and pyloric region. This suggested that the neurons might play a more important role in small intestine.
